' The present-invention relatesto'improvements'in. sugarcane Crushers and more par ticularly L to "improved devices for stopping and regulatingthe' advanceof sugar-cane 1n 5 the. crusher'supply chute. i 5

The object of the invention is; to provide stop devices in asug'ar cane mill for relieving congestion in cane chutes and for regulating the cane feed-to'maintaln a unlformdepth of .rollsysa'id devices engaging the-contents of saidchute at the vto-p and atthe bottom t-he'rer In canelmills, the crusher rolls and-the first mill rolls are usually driven together,

vand in many instances the first mill-rolls do not take the feedof the cane coming from the V I p p of the 'devicei iseillustrated, and it willbe,-un-.

derstood-changesin the Construction andiprd crusher rolls at the same rate of speed, which is due either to change of speedin mills, faulty roll setting, badlyworn'trash turner plate in the first mill, or change'in variety of sugar cane etc.- vThe cane therefore piles upin front of the crusher rolls completely choking them up, and. these rolls'keep on moving, but no] productive action: occurs. To'clear the mill of this accumulated cane, the services offour,

-,or five men With steel .hookswiththe loss-of considerable time, is required, andmoreover the steel hooks often become lost in the;eane' and are carried through the. entire mil-l causing considerable damageto the rolls, and putting. the entire I'nill out of operation, resulting in considerablerloss.

To overcome these difiieulties, 'Ihave provided apoweropera-ted cane feed stop. and, k V v h 1 rolls 11, are journalledin' suitable blearings 12.and are driven with the first mill rolls 13' e regulator properly-located forwardly of the crushing rolls' which may beoperated'by' manipulatingthe handle of a-four Way hydrauliccontrolvalve convenientlyloc'ated; the I 4 I ar'cuate-cast1ng 15jform1ng the, mouth-of a Isugar' canechute 16 which communicates'vvith' operation being rapi d and positive.

The inventive features/of the improved de vices reside in the provision of stop devices, one entering the cane chute from below, and the other engaging the canejin the chute from above, the stop devices being operable in opcam in said chute in its travel to the crusherv v .tinue to the crusher rolls," 1 v The invention also; includes the provision.-

-' of stationary cane levelers consisting of Fig. 1, point.

The depth of cane in the chute should at h alltimes be about four feet and tomaintain 5 this depth an operator may be stat'ioned at the c handle of the fo'uri wayi hydraulic valve to] operate it, when necessary; to retard] the feed 'and permit the cane tojbulild up tofthat dept-h, after which the can'eisreleasedtocon;

designates the mill frame in whichi crusher 3'0 in any approved manner. I supported on. a post 14 or the like is' an may be welded or otherwise secured 'to the sides of the arcuate casting 15; said casting being formed with side bearings 20, (one only being shown) in which a pulley 21 is journailed to support a travelling cane feeding conveyor 22.

Located between the sides 19 of the cane chute 16, are cane levelers 23, to level OK the incoming cane as it enters the chute from the conveyor.

The retarding devices of the invention preferably include a rock shaft 24, extending across the chute 16, with its ends journalled in bearings 25; one end being projected to receive an afii xed sleeve 26 formed with a backwardly extending upper arm 27', having its end pivotally connected. as 21.11.28, to the upper end of a downwardly and forwardly extending link member 29, which in turn ispivoted as at 30, to the forward end of a lower arm 31 which has a sleeve 32, keyed to a crossrockshaft 33, mounted in suitable bearings 38 and having integralbackwardlydirected arms 34', pivoted as at 35, to. a set of pointed stop pins 36, extending upwardly loosely through holes 37, in the bottom 18 of said chute.

Locked t'o'the cross shaft Qhisa sleeve or sleeves 38, with which a number of arms 39 are associated,- and are secured together rearwardly of the shaft 24 by a tie bar 40,and

said arms 39 are formed with integral down wardly directed pointed hooks 41, forming an alined set ofspiked devices adapted to enter the sugar cane inthe chute from above.

Suspended through a loose joint 42, from a bracket 423, located at the transverse center of the chute bottom, is a hydraulic cylinder 4A of the usual type, which; is connected at its opposite ends as at 45 and i6,. through flexible steel hose 47 and suitable piping l8 and 49 toa four way hydraulic valve 50, having inlet and outlet pipes 51 and 52 respectively and an operating handle. 53. a

The piston rod 54- of the hydraulic piston 44, is pivotally connected. as at 55',to a short arm 56, formed with. the arm 34 constituting the central arm of' the 34 group above described.

As above stated, the pins .36 onthe arms 34' are pointed as are the hooks: a1, and in the claims I shall at times refer to:these parts as spiked, meaning. pointed, and further,

Imay in the claims, for better identification, refer to the arms 27 and 31, of the uppenand lower shafts 24. and 33, as crank-arms.

What I claim and desire to secure by Let- 1.
